Doubt we’ll get any useful low level documentation out of Broadcom on the GPU for 3D or video acceleration. The Raspberry Pi is already stated to have closed source binary libraries for 3D and a limited set of HW accelerated video codecs.

The SoC doc that was released is nice but even without it, you would have been able to extract most of the information from examining the Linux driver sources. Broadcom is notoriously bad for releasing documentation so I don’t hold out much hope for any useful GPU docs but the SoC docs is a good start!

I’ll be getting one or two after the initial batch. I don’t have any rush for one at the moment so I can wait and let somebody else get in there first.
